Specification of Letters Patent.

Patented Apr. 9, 1918.

Application filed February 23, 1917. Serial No. 150,506.

To all whom it may) concern Be it known that I, FRANK "E. SMITH. a citizen of the United States, residing at T0- peka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

This invention relates to improvements in window screens and the primary object of the invention is to provide a window screen constructed to permit flies and other insects on the interior ofthe dwelling to pass out through the screen through a passageway designed to eliminate the possibility of the flies returning through the passageway.

Another object of the invention is the pro vision of a screen of this character constructed to permit the flies to escape from the interior side of the screen while eliminating any objectionable structurethat would tend to exclude light or air from the dwellmg. I

A further object of this invention is the provision of a window screen which consists of comparatively few parts and is simple in construction,butdurable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which:

Figure 1 is an elevation of the outside of the screen.

Fig. 2 is an elevation of the inside of the SCI'GGII.

Fig. 3 is a section on the line 3-3 of Fig.1.

Fig. 4; is a section on the line 4l of Fig. 1, and

Fig. 5 is a section on the line 55 of Fig. 1.

Referring to the drawing, wherein is illustrated the preferred form of my lnvention,

and in which like numerals of reference indi-.

tached to the frame in the usual manner.

The top marginal edge of the screen panel,

however is provided with a continuation which is projected outwardly at right angles from the panel thereby providing the upper wall of an exit opening 7.

Fastened to the inner side of the frame bars 1 and :2 is av pair of short supplemental frame bars 8 which project downwardly from the top of the frame for any suitable distance. The upper ends of these members 8 are connected by a short frame bar 9 thereby providing a frame for the supplemental panel 10. As clearly shown by Fig. 4 of the drawing, this panel 10 is slightly spaced from the panel 6 to provide a passageway 11 which has its inlet at the lower imarginal edge of the panel 10. The upper end of the panel 10 is provided with a short extension which proje ts outward y a ight angl s to form the lower wall of the exit opening 7, the latter being a c tin ation f t e paisageway 11,.

Attached to the outside of the top frame bar 3 is a strip of wood or other suitable material which forms a coping 12 extending considerably beyond the exit opening 7 thereby serving as a projection during a rain storm and also acting as a baffle for the purpose of preventing the flies from finding the exit opening 7 when attempting to enter through the screen.

The lower marginal edge of the panel 10 is fastened to a small disk-13 which is interposed between the panel 10 and the screen 6 thereby providing a brace for the central portion of the panel 10 for preventing the marginal edge thereof to be bent upward thereby closing the opening to the passageway 11.

When the flies on the interior of the dwelling light upon the panel 6 they will follow their natural inclination to seek the top of the screen and in. doing so will pass through the passageway 11 and then out through the exit opening 7.

From the foregoing it will be observed that a very simple and durable window screen has been provided, the details of which embody the preferred form. I desire it to be understood, however, that slight changes in the minor details of construction may be'made without departing from the spirit of the invention or the scope of the claims hereunto appended.

I claim:

1. A screen of the character described comprising a main frame adapted to fita window casing, a screen mounted in the mam frame and slightly longer than the same, one end edge being turned at right angles to extend outwardly from the frame adjacent one end thereof, a supplemental panel of screen mounted in spaced relation to the main panel and connected to the top of the frame the upper end of the said sup-. plemental'p'anel being extended and turned at right angles to lie in spaced relation to and parallel with; the said projection of the main panel.

2. A screen of the character described comprising a main frame adapted to fit in a window casing,

ingfrom the top thereof, a main panel of screen mounted in the frame and slightly longer than the same, the end edge of the said panel being turned outwardly at right angles and projected beneath the said coping,

a supplemental vpanel mounted in spaced re-V lation to theimaln panel and providing a passage Way between the main panel and the supplemental panel, one end of the said supplemental panel being turned at right angles above the extension of the said main panel and beneath the said coping to provide an outwardly projecting passage ,Way between said panels and beneath the copin 3. A; screen of the character described 7 comprising a mainframe adapted to fit in tcpies of this patent may be obtained for five cents each, by address a Washington, D. G.

a coping attached to the exterior of the window casing and pro ecta window casing, a screen mounted in the main frame, a supplemental panel of screen mounted in spaced relation to the main panel for providing a passageway extending across the width of the main panel and upwardly to and slightly beyond the top edge of the main panel, the upper marginal edges of both the main panel and the supplemental panel being extended outwardly at'right angles to provide an exit opening )anel for rovidin a mtssa 'ewa extendin across the width of the main panel and upwardly to and slightly beyond the top edge of the main panel, the upper marginal edges of both the main panel and the supple "mental panel being extended outwardly at r1ght angles to provide an emt opening. from the said passageway,and means for bracing thelower marginal edge of the said supplemental panel. 7 i I V W In testimony whereof I afiix my signature in presence of two witnesses.
